Operation Safe Arrival will run from midnight on Friday December 20, 2019 and end at 11.59pm on New Year's Day.

NSW Police Western Region Traffic Tactician Inspector Ben Macfarlane urged drivers to be patient over the festive season.

"We have managed to keep the road toll under 2018 totals so far this year which is due to a combination of motorists heeding our road safety messages and driving responsibly," he said.

"We want that to be carried right through to the new year."

Inspector Macfarlane said double demerit points would be in force throughout the period for speeding, seatbelt, mobile phone and motorcycle helmet offences.

"Double demerit points is a tool we use but really the best way to avoid being booked is to drive safely, obey speed signs which are highly visible and of course be well aware of what the road rules are," he said.

"Drivers should have a plan and prepare for their trip before they go. That includes making sure their vehicle is roadworthy, the driver is up to the trip and is well rested and not affected by a big night prior to driving."

Avoiding distraction in the vehicle is also a good way to arrive safely at your destination Inspector Macfarlane said.

"Get your passenger to control the entertainment and adjust the air conditioning in the car, there is no need for the driver to be worrying about those things," he said.

"We wish motorists a merry and a safe Christmas, do not place yourselves or others at risk through poor decision making and of course we want everyone to arrive at their destination safely."

Traffic and Highway Patrol Commander Assistant Commissioner Michael Corboy said police will be out in significant numbers this summer, from major roads and highways to back roads in rural areas.
